thermodynamics Flashcards
which substance has the highest specific heat capacity?
water
the device used to identify an unknown metal is a _____
calorimeter
calorie
most common units used for measuring heat
temperature
measure of the average KE of the particles in a substance
celsius scale
0 degrees celsius- freezing of water
100 degrees celsius- boiling of water
farenheit
32 degrees Fahrenheit- freezing point of water
212 degrees fahrenheit- boiling point of water
kelvin scale
0 = no KE (particles stop moving)
👇🏾
absolute zero = -273 degrees celsius
heat
energy transferred between objects that are touching
thermal equilibrium
when 2 or more objects in thermal contact reach the same temperature
thermal contact
energy transferred between objects that are touching
adding heat _____ an object, and cooling objects ________ it
- expands
2. contracts
Q = m 🔼t
Q = heat in joules or calories ( gained or lost )
M= mass (grams)
🔼t = change in temperature
c = specific heat capacity
